Question

I have 2 arrrays, And i need return TRUE or FALSE when 2 arrays matched each other. also un-ordered arrays should return TRUE if results matched, but only should return true if both arrays have same values.

//This should return TRUE
$array_One = array('test1', 'test2', 'test3');
$array_Two = array('test1', 'test2', 'test3');

---

//This should return TRUE
$array_One = array('test1', 'test2', 'test3');
$array_Two = array('test1', 'test3', 'test2');

---

//This should return TRUE
$array_One = array('test1', 'test2', 'test3');
$array_Two = array('test1', 'test3', 'test2');

---

//This should return FALSE
$array_One = array('test1', 'test2', 'test3');
$array_Two = array('test1', 'test2');

I tried few methods, including array_key_exists by using foreach, But it does not returned the expected result. This should return ONLY one TRUE or FALSE when arrays matched.

If you just need to know if two arrays’ values are exactly the same (regardless of keys and order), then instead of using array_diff, this is a simple method:

<?php

function identical_values( $arrayA , $arrayB ) {

    sort( $arrayA );
    sort( $arrayB );

    return $arrayA == $arrayB;
}

// Examples:

$array1 = array( "red" , "green" , "blue" );
$array2 = array( "green" , "red" , "blue" );
$array3 = array( "red" , "green" , "blue" , "yellow" );
$array4 = array( "red" , "yellow" , "blue" );
$array5 = array( "x" => "red" , "y" =>  "green" , "z" => "blue" );

identical_values( $array1 , $array2 );  // true
identical_values( $array1 , $array3 );  // false
identical_values( $array1 , $array4 );  // false
identical_values( $array1 , $array5 );  // true
